hi guys, i have a HUGE problem, when i use start => RUN and i TYPE cmd, it opens c:/windows/system32/cmd.COM not cmd.exe . CMD.exe still exist, but it can't be opened within the start => run method. If i open cmd.com in notepad is just see the letters MZ... i have tried to delete it, but it can't be deleted (not even in save modus). I have run all the spyware  scans (spybot, ad-aware, spywaredoctor, spywareblaster, spysweeper,...) and all the antivirus scans (nod32, ewido, norton)

[glb]can somebody help me[/glb]

p.s. my os is windows xp professionalFirst off, make sure you're not running both Norton and Nod32 at the same time, as having two anti-virus utilities running at once can cause conflicts.

It sounds like you have a worm that creates .com files under system folders which are launched before the .exe counterparts.

It is likely you have one of the following:

Picrate
Alcra

Read up on those links and see if you can locate the offender files. Make sure to have the "show hidden files and folders" in folder options CHECKED.

with regardsGoogle for Killbox.exe and delete it with that.thanks, your links helped, thanks for you responses! i appreciated it
